What's going on with me?

Joanne • 33yrs old.. married to my king.. mother of 1 ttc #2
I am so emotional right now. Crying over things that are not necessary to cry over. So sensitive. Smallest things are setting me off. Complete overreactions.. breaking out, which I never do, cramps off and on, not bad but there, exhausted but not due for af for 9 days. What is wrong with me? Any thoughts or suggestions to over come my emotions. Husband totally supportive and that makes me sad to like I'm upsetting him when he swears I'm not. Am I going crazy?
